Yendall was buried back in the field on the $2.20 favourite and at the
mercy of lighter-weighted runner Rael Rules ($5), which kicked clear at
the top of the straight after setting a modest pace in front.

Bioko was angled away from the rails by Yendall on the turn and balanced
up down the middle of the track but was giving Rael Rules a big start.

It wasn't until the final 100 metres that he closed quickly on the
leader and levelled up centimetres from the winning post.

His momentum
was rewarded with a short half-head victory, with Gun And Power ($5) a
further 1 lengths adrift.

"I thought this horse's last 100 would have been exceptional," said Edwards, who trains in partnership with Bruce Elkington.

"It (Rael Rules) had every chance to beat us.

"He (Bioko) goes good for Dean. This horse has had eight or nine runs
with Dean and he would have won four of them. He's a bit of a trick
horse. You have to kid to him and kid to him."

Bioko, which lumped 59.5 kilograms, has been in rare form this campaign,
winning at three of his 10 outings and earning connections $30,000.
